Section 341(c) in Police Regulations, Bengal , 1943
(c)It is important that the method of the supervision exercised should be determined with reference to the class of crime to which the surveille is addicted, and should not be allowed to become stereotyped, For instance, a dacoit or burglar should obviously be looked up at his home at night, and, if necessary, several times the same night, especially during the dark nights; but in the case of a pick-pocket it would be of greater use to have him carefully watched at hats and other places which he is known to frequent. In the case also of swindlers, druggers, utterers of counterfeit coins, forgers, etc., it is obviously useless to depend upon night visits. Such visits can serve no useful purpose and are a mere waste of time. What the station officer should aim at is to get early information of the absence of a criminal addicted to any of these crimes and to note the fact of the absence in his registers, and on the return of the criminal question him as to the cause of his absence and verify his statement without delay. No detailed instructions can be laid down, but officers are expected to use their intelligence and make the surveillance as effective as possible.
